1 This invention relates to guard Windows, al.. though not necessarily so limitedand moreparticularly to a closure assembly for aventilating area for the same.

In guard windows, such as psychiatric guard windows, detention windows and. windows for use in prisons and the like,wher ,ein the muntin bars.

or bars simulating muntinbars, are used. as detention bars, certain. spacesv may be leftvacant or unglazed for usel as aventilating area. When this is done,l it may be, necessary to provide av closure for the,A Ventilating. area.

An object of this. invention. is, to, provide. an.

attachment for the guard. window, suchv that the.

closurev may ber slid from a. closed position to an open position and viceversa, furthermore, the closure may be, actuated into1 another position where it may. be easily cleaned,` repaired, painted, reglazed, reputtied and the; like, without being detached fromthe guard window.

Another objectV ofl this invention, is to. provide a guide for use Witha sliding closurefor a ventilating area, wherein thev guide is` jointed, so.

that when the closure is actuated into open. po sition one portion oi the guidemay be rotated so as to turn the closure inside out..

Other objects and advantages reside, in the construction of parts, the combination thereof. and the mode of. operation,I as willbecome more.

apparent from the. following.y description.

Referring.` to the drawings, the guard window orA detention window proper includes a top frame member II),4 the horizontal muntin. bars I2 and theverticalmuntin bars I4. These may be conventional muntin barsT-shaped in cross section, which, in addition to functioningasmuntin bars, also function. as detention. bars or guard bars, preventing the ingressor egressof human beings throughthewindow. The spaces I'in the upper half..v of the, window, as, seenin Figure 1, are glazed. The openings. I84 between the guard bars in the lower half, asviewed in Figurev 1, remain unglazedand may beI used as a Ventilating area. The window. assembly described thus far may be a conventional, Window.

The. spaces left vacant for.. a Ventilating area may extend. to. the bottom of the Window and may extend acrossthe width.. of the window,v or these. spaces may. constitute an area less than one-half. the.' height of. the. Window and an area less, than the Width of thev Window. This is a matter ofV4 choice, depending entirely upon the particular requirements.. Furthermore, ythis area forming, the, Ventilating area mayv be relocated after the. windowV is.insta1led,.so as to better meet the requirements either due to changed conditions. or dueto. conditions thatV had not ybeen anticipatedatthe time the Ventilatingarea was first located. Also,.the Ventilating area may be changedin size from time to time by merely providing, aproper attachment for closing the Ventilating area, which attachment will now be described..

attachment includes a lower frame portion 20 that is. provided'with a sill member 22, having a horizontal portion 24, and a pair of dovviiwardlyk projecting flanges 26 and 28 straddling the upwardly directed flange 30 of the transverse. muntin bar I2` extending across the bottom-of the Ventilating area. The flange 26 makes-a line contact .withthe flange, to thereby prevent Waterbeing drawn through the juncture betweenthe sill 22and. the supporting muntin bar I2 by. capillary attraction. The flange 28 is provided with-ahorizontalflange portion 32 seatedi against theface of the muntin bar I2 l and providing alcavity34.for insulating material,

the closure rests when in closed position, as will be described more fully later.

As may best be seen by referring to Figure 3,

' the stationary lower frame portion 20 includes a pair of lateral channel members 50, one on either side of the Ventilating area, each provided with an inwardly directed channel v52. The wall 54 Aof each member 50 is provided with 'a channel supporting a strip of weather-proong material 56, sealing the juncture between member 50 and the adjacent vertically disposed muntin bar |4. Member 50 may also be provided with a flanged portion 58, to which a woven wire screen 60 is secured in any suitable manner. The sill 22 and members 50 are joined by a mitered joint, as best seen in Figure 6. An L-shaped bracket 51 is riveted by rivets 59 to the sill 22 and to a member 50 to provide a rigid corner. Across the top of the stationary frame portion 20 extends a bar 10, as best seen in Figures 2 and 4. This bar 10 is provided with a channel housing a strip of weather-proofing material 12, so as to seal the fourth side. Member provides a support for the upper edge of the screen 60. Members 50 and thebar 10 are secured together by L brackets 6|, as best seen in Figure 5. Member 10 is also used to fixedly secure the closure in position by suitable means which will now be described.

A lug 14 is positioned in the corner between two intersecting muntin bars, one of which extends across the top of the Ventilating area. A bolt 16 provided with a round head is positioned against member 10 and held in position by a suitable nut 18 that preferably has a round periphery and may be removed only by the use of a specially designed tool, so as to prevent the inmates from removing the fixed portion 20. The bolt 16 cooperates with the lug 14 to clamp the xed frame portion against the muntin bars surrounding the Ventilating area. The flange 26 prevents outward movement from the bottom.

The stationary frame portion 20 provides a frame for a movable closure 80, glazed by suitable window panes 82 seated in the bottom frame member 84, the top frame member 86 and the side frame members 88. The bottom frame member 84 of the movable closure is provided with an inwardly directed lip portion 90 that prevents condensation which may form on the glass or window pane 82 from running down so as to seep in between the bottom frame member 84 and the flanges 40 and 42. Angle bars 8| cooperate to form a T-shaped light weight muntin bar for the movable closure 80.

The movable closure 80 may be raised so as to open the Ventilating area. In order to provide a guard for the closure 80 above the fixed frame, an auxiliary frame 92 is located above the fixed frame, which auxiliary frame will now be described.

Members |00, one forming a continuation of the side members 50 and identical in cross sectional area, extend upwardly from members 50 and are attached thereto by suitable hinges |02. A transverse angle bar |04, as best seen in Figure 2, connects the tops of members |00. Members 50 provide channels for the Ventilating closure to be raised, so as to open the Ventilating area. The screen 60, however, extends over the Ventilating area, even though the closure 80 is raised into up position.

In order to prevent the auxiliary frame including members |00 and |04 from tipping about the hinges |02, so as to drop from the position shown in Figure 2 to that shown in Figure 4, members 50 are secured in position by studs |06, only one of which has been shown. Each stud |06 is provided with a round head |08 that cannot conveniently be unscrewed from the tubular nut-like member I|0 without the use of a special tool. Tubular nut-like member ||0 is iixedly secured to a vertically disposed bar ||2 located between the glazing ||4 and the downwardly projecting flange of top member I0 and the upwardly projecting flange of the adjacent muntin bar l2. The bolt |06 cooperates with the tubular member I I0 to removably clamp the auxiliary frame in a stationary position.

In the event it is found desirable to wash the outside of the Window pane of the closure, or in the event a window pane is broken, the window pane 82 may be replaced by opening the closure so as to be located between the bars |00. Then by unscrewing the stud bolts |06 from the tubular members ||0, the closure 80, together with the frame members |00 and |04, which constitute the auxiliary frame, may be moved into the position shown in Figure 4. When in this position the outside of the glazing 82 may be washed, the putty |20 may be repaired or in the event of a broken window pane, it may be removed and a new window pane 82 inserted and re-puttied in readiness for use. When the closure has been serviced, the auxiliary frame, including members |00 and |04, together with the closure 80, may be raised to the position shown in Figure 2, the stud bolts replaced by the use of a special tool, so as to secure the auxiliary frame in position, and the closure dropped into the full line position shown in Figure 2.

In the modification disclosed in Figures 7 to, 10 inclusive, the lower frame portion |30 is sub-l stantially identical to the corresponding portion in the preferred embodiment. The auxiliary' frame |32 is substantially identical to the aux` iliary frame |00. The closure |34 is slidablymounted in the main frame |30 and the auxiliary frame |32.

As may best be seen by referring to Figure 8, the side frame member |36 of the movable closure |34 has attached thereto a weather stripping spring |38 that may be secured at |40 to the side frame member |36. This weather stripping spring |38 is provided with a small loop |42, positioned between the auxiliary frame |32 and a pair of ribs |44 and |46 integral with the side frame member |48 of the main frame |30. A loop |50,

formed on the end opposite the loop |42, provides a bight into which the flange |52 projects. This weather stripping member is preferably made from suitable resilient material, such as brass.

A channel-shaped operator |60, pivotally mounted upon a pivot |62 extending into the main frame and supporting a spacer member |64, functions to hold the auxiliary frame in a tilted position when released and in a xed position when locked.

A shoe |10 is pivotally mounted upon a pivot |12 xedly mounted in the side frame of the auxiliary frame |32. This shoe |10 is mounted in the upper end of the operator |60. In order to limit the angle of inclination of the auxiliary frame |32, a stop |14 is xedly mounted in the channel of the operator |60, so as to arrest the movement of the shoe |10. The position of this stop determines the angle of inclination of the auxiliary frame when swung into open position.

The operator |60 is also used to lock the auxiliary frame 32 against lthe main frame of the 5, window. By vadjusting the auxiliary frame into. dotted position/the operator |60 will then extend parallel to the sides of the iixed frame and to the side of the auxiliary frame. The operator |60 may be locked in this position by means of a cam-like latch |80 pivotally mounted upon a pivot |82. This cam-like latch |80 is mounted for limited position about the pivot |82 and may be projected out through the frame through a slot |84 into 'the full line position shown inFigure 8, so as to engage the side ofv the operator |60 to prevent this operator from rotating about the pivot |62, thereby locking the auxiliary frame into position parallel to the main frame.

Although the illustrating device discloses a closure that is raised to open the Ventilating area, this closure may be lowered to open the ventilating area in the event the Ventilating` area is positioned above the glazed area. Furthermore, the Ventilating area could be located to one side of the glazed area, in which event the auxiliary frame could be laterally disposed with respect to the Xed frame for the closure. When thus arranged, the closure could be slid sidewise to open and close the Ventilating area, Also, the auxiliary frame might extend over the Ventilating area and the xed portion of the frame extend over the glazed area.

Furthermore, the closure assembly, instead of being located on the inside of the window, may be located on the outside of the window. Especially is this desirable when the closure is opened and closed by remote control mechanism, such remote control mechanism being located out of reach of the inmates.

The closure assembly described vherein has been shown in connection with a guard or a detention Window. The closure assembly, together with the guides therefor, could be used in connection with other types of windows, as for example, oflice windows, in which event there may or may not be muntin bars extending across the opening forming the Ventilating area.

Although the preferred embodiment of the de,- Vice has been described, it will be understood that within the purview of this invention various changes may be made in the form, details, proportion and arrangement of parts, the combination thereof and mode of operation, which generally stated consist in a device capable of carrying out the objects set forth, as disclosed and defined in the appended claims.
